Filed: 1964-06-12
Abstract: 1,058,839. Inverting; frequency changing. WESTINGHOUSE BRAKE & SIGNAL CO. May 17. 1965 [June 12, 1964], No. 24465/64. Addition to 1.047.681. Heading H2F. In an inverter circuit as described and claimed in the main Specification 1,047,681. wherein a storage capacitance is charged through first switching means and discharged through second switching into a resonant output circuit at a frequency which is lower than the resonant frequency of the output circuit, duplication of the first switching means is provided so that the capacitance may be charged in either sense. As shown in Fig. 3, which is a bridge, capacitor C1 is charged in one sense through rectifiers CR1, CR11A and discharged through a saturable reactor SR into a tuned output circuit C2L2. It is charged in the opposite sense through the rectifiers CR1A, CR11. The resonant frequency of the output circuit C2L2 is higher than the discharge frequency of C1 In another embodiment (Fig. 1, not shown), which is an embellishment of Fig. 9 of the main case the capacitance constitutes two capacitors which are oppositely charged and discharged in series through the output circuit to give an enhanced output voltage. A further arrangement (Fig. 2, not shown) provides a multiplicity of subcircuits as described above discharging sequentially into a single output circuit, so as to give longer time for the recovery of the switching rectifiers.

Filed: 1970-05-20
Abstract: 1313708 Converting; control of DC motors GENERAL ELECTRIC CO 20 May 1970 [4 June 1969] 24505/70 Headings H2F and H2J [Also in Division H3] In a reversible current rectifier or frequency changer of the type in which first and second thyristors must not be simultaneously conductive, the voltage across the thyristors is monitored by a circuit arranged to short-circuit one winding on a transformer whenever the voltage across the thyristors exceeds a predetermined value greater than the forward voltage drop. The invention may be applied to control of a reversible D.C. motor or, as shown, to a frequency convertor comprising inverse parallel connected three-phase bridges of thyristors 16, 18, 20 (only three shown) and 22, 24, 26. When reversing the output polarity, triggering of the inverse bridge will be inhibited until the thyristors of the conducting bridge turn off, when zener diode 63 will break down, turning on transistor 73 and short-circuiting winding 75 of a transformer. The short circuit will be reflected across winding 80 so that increased voltage will be developed across resistor 79 which is used to allow triggering of thyristors of the inverse bridge. A complementary circuit 65, 67, 71 monitors negative voltages. A common transformer 83, 84 may be used for two of the phases. The conduction angle of the thyristors may be modulated (Fig. 3, not shown) so that the resulting low frequency output tends to be more sinusoidal.

Abstract: 644,881. Dishwashing machines. PAINE, R. M., and PAINE, S. W. T. Sept. 5, 1947, No. 24542. [Class 138(i)] A dishwashing apparatus comprises a reservoir to contain cleansing liquid, means for supporting the dishes, an air-lift pump consisting of a tube within and communicating at its lower end with the reservoir and communicating at its upper end with an outlet or outlets above the reservoir and a pipe adapted to supply air to the said lower end, which pump raises a discontinuous stream of liquid to the level or above the level of the dishes, and means for dispersing said stream in jets over the dishes. As shown in Fig. 1, washing liquid in a reservoir 11 depending from the bottom 9 of a container 1, is forced up a tube 12 by compressed air admitted to the lower end of the pipe through a nozzle 13 and violently dispersed from a conical head 50, Fig. 9, mounted on the upper end of the pipe, to spray over crockery. The head has a plurality of oblique slots 51. Alternatively it may be provided with perforations and be of cylindrical shape in lieu of a cone. The tube 12 is supported in the reservoir at its upper end by a conical strainer 12a. Crockery is supported on a removable wire framework carrier mounted concentrically with the head 50 and comprising wire rings 54, 55 connected by wires 55a to a base ring 53. Plates are supported in slots in the ring 53 and a concentric ring 52, so that they lie along chords of the rings and also lean backwards. The nozzle 13, which is integral with a junction 17 connected to the bottom of the well by a flange 18 is supplied with compressed air by a centrifugal blower 14, through a conduit 15 and a non-return valve 16. A quantity of hot water is applied to the junction 17 from a T-union 19, a pipe 20 and a valve 21. The temperature of the water, which is recirculated after spraying, is boosted by an electric heater 26 surrounding the lower end of the tube 12. The right hand side of the Tee union is connected to a drain outlet 31 by a water trap 30, a pipe 23 and a drain valve 24, which valve is closed during the washing operation. Air is released from the container, which is sealed during the washing operation by a lid 2, through an opening 28, covered by a strainer (not shown), and a pipe 29 the lower end of which is situated beneath the level of the water in the trap 30. The lid is secured to the container by a bridge piece (shown only in part) actuated by a handwheel and a spindle 5. The head 50, with a handle 67, Fig. 10, may be formed integral with a wire carrier structure designed particularly for glasses comprising rings 61, 62, bent wires 63 and having a base 64. The structure can be fitted over the air pipe 12 with a sealing ring 66 disposed between the head 50 and the top of the air pipe. The Specification also describes alternative forms of wire framework carriers and a stand for sup porting a carrier prior to loading it into the container.

[Also in Group XXXV] A predetermined positive, zero or negative frequency temperature characteristic is arranged in an oscillatory circuit comprising a coil and a condenser by variably compensating the positive temperature characteristic of the condenser's capacitance and the coil's inductance by making the coil former of a material e.g. titanium dioxide whose dielectric constant has a negative temperature characteristic and by selection of the ratio of the coil's self-capacity to the total capacity of the circuit. The coil may comprise a former 1 of such material shaped as a solid or hollow cylinder, and having helical grooves 3 on the outer or outer and inner faces, to which respectively a winding 3, or parallel connected windings 3, 4, of a noble metal are applied by fusion. The self-capacity of the coil is chosen by selection of the winding pitch, the depth and width of the grooves, the former wall thickness, and by partly or wholly metallizing the former bore if unwound and hollow. The coil may alternatively comprise a spiral winding on a disc-shaped former and having similar arrangements for chosing its self-capacity.

Abstract: 1,131,877. Electric detonators. DYNAMIT NOBEL A.G. 3 June, 1966 [4 June, 1965], No. 24958/66. Heading F3A. In an electric detonator comprising a case 1 defining a chamber for an electrically conductive priming composition, the electrodes 5<SP>1</SP>, 5<SP>11</SP> extending through the electrically insulating, thermoplastics base 2 are formed by thrusting a staple-like member through the base from the inside of the chamber to the outside of the case, thereafter bending the protruding ends of the staple-like member towards the base to form the outer ends of the electrodes, and cutting the web of the staple-like member so as to form two inner ends with a gap therebetween. The staple-like member is driven through the base 2 in a manner similar to that used in a stapling machine by, for example, impact or a sudden powerful pressure, the protruding legs of the staple-like member being bent over by a baseplate provided with suitable depressions. The cutting of the web is effected by a cutting or milling tool or by a striking action, in which case the cut ends of the web are simultaneously pressed into the base. The chamber for the priming composition may consist of a main compartment 4 and two side compartments 6. The main chamber may taper away from the base 2 and be of circular, square, or star-shaped crosssection.
